Not picking on SKW in particular but you can understand how it happens. Some people are never going to get the call due to past training failures, too many DUIs or other personnel issues, etc. others just got screwed by circumstances during the lost decade or being in a regional that died (or like Comair was killed) and having to start over a time or two and even if they COULD now now get hired at a major they never sit in the left seat again, might not even ever get off reserve again, and the pay hit they'd take the first couple years as a major FO would never be offset by the salary increase they'd get in the few years they had left. Besides, many have been in one base for the last 10-15 years and have grown deep roots there. Are they really going to want to move to a major base far away? Or commute to reserve in a crash pad rather than stay where their family is and where they have seniority up the ying-yang?
